construction period. Evaporation of the moisture contained in the concrete should be avoided sinceit is needed for the setting process. The water you splash on the concrete will evaporate and at thesame time keep the concrete moist.figure 5.105.1.5 Preparation of the tank roof reinforcementMark a circle in your preparation area with the radius of the tank reinforcement. Put an uprightcement block in the centre about 450 mm high. There are different ways of cutting the reinforcementmesh. The roof has to be a dome shape, so the cement block marks the highest point. Make surean overlap of at least two squares, about 300 mm, is given and tie the reinforcement well together.Whether this has been achieved can be proved by lifting up the dome. It should be well stabilized inone piece. Fig. 5.11 shows one way of cutting the reinforcement mesh to save material. After alltriangles extending the circle are cut off, cover the dome of rein" forcement mesh with chicken wireand tie it well to the mesh. Overlapping of the chicken wire is important. 200 mm is required, Fig.5.12.figure 5.1136
